thank you, the Volvo dealer told my a bolt had stripped going to my axle. They said that would take care of the problem. But when I got home it was still doing it. So I will take it back on Fri. It does sound like something in the shifter. I can hear a cable sound when I push on the peddle lightly. I hope it isn't my transmission :(

I have been into the Volvo shop 3 times in the last 5 days :( so I thank all of you for your idea about the shift cable. I have always had Volvo service my car and I am not hard on my car. They also said I need brake pads but the rotors are under sized. I have never replaced them before so how could they be. Also they said my right CV boot needs replacing but they said I have an after market axle. I have never put on an axle before so how could in not be the right one. I have been the only owner. Or is it that I am a girl :)

If you're lucky this is a shift cable, but on a 2001 V70, there's a good chance the transmission is going out. I agree with Zee, find a good Volvo shop to look at this. Find some here: http://repairpal.com/directory?address=93428&car_brand_names=Volvo
